I was at Atlantis over Christmas and delightfully surprised to see IIDX and pop'n there.
Haven't been in Atlantis for like 2 years and I come back to find those two machines, lol. First time I got to play IIDX and pop'n at the arcades.
I even took pictures of me hugging the machines in the morning before I left.
Got a few funny looks from people, hahaha.
